AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
256 PM CDT TUE JUN 22 2010

.DISCUSSION...

DAYS 1-2...

RIGHT ENTRANCE REGION OF AN UPPER JET ALONG WITH AN ASSOCIATED
UPPER LVL S/W TROF WILL CROSS NE CO/NW KS LATE TODAY WITH ALL THE
MODELS FAIRLY CONSISTENT WITH THE TIMING AND TRACK OF THIS UPPER
LVL SYSTEM EARLY TONIGHT. SFC ANAL FROM 19Z PLACED A SFC BOUNDARY
ACROSS OUR FAR W/NW CWA SO AS TEMPERATURES APPROACH THE CENTURY
MARK IT LOOKS LIKE THERE IS STILL A DECENT CHANCE FOR LATE DAYS
STORMS ALONG THESE BOUNDARIES AS THE UPPER LVL SUPPORT IMPROVES.
CURRENT FORECAST APPEARS TO HAVE A DECENT HANDLE ON WHERE THE
BETTER CHANCES WILL BE LATE TODAY AND EARLY TONIGHT AND ALSO AGREE
WITH LATEST SPC ASSESSMENT THAT ANY STORM THAT DOES DEVELOP WILL
LIKELY TO PRODUCE HAIL, STRONG WINDS AND PERIODS OF HEAVY
RAINFALL...ESPECIALLY IN OUR NW CWA. IN THE FAR WEST TONIGHT
GIVEN THE WARM MID LAYERS THESE STORMS WILL BE MOVING INTO WOULD
EXPECT SOMETHING SIMILAR TO LAST NIGHT. LATE DAY STORMS WHICH DO
DEVELOP WILL WEAKENING AFTER SUNSET AND THEN DISSIPATE. THE NAM
DID A PRETTY GOOD JOB ON THE EASTWARD OF EXTENT OF STORMS LAST
NIGHT SO HAVE DECIDED TO FOLLOW THIS TREND ONCE AGAIN. FURTHER
NORTH STORMS SHOULD LAST LONGER HERE GIVEN THE LOCATION OF THE
UPPER LVL DYNAMICS.

BY EARLY WEDNESDAY A COLD FRONT REMAINS PROGGED TO CROSS SW KS
WITH LITTLE IF ANY PCPN EXPECTED WITH THIS FRONT DURING THE FIRST
HALF OF THE DAY. THE EXCEPTION TO THE DRY FROPA REMAINS TO BE OUR
EXTREME ERN CWA AND MAINLY FROM THE NAM. BY WEDNESDAY EVENING
HOWEVER BOTH THE NAM AND GFS ADVERTISE IMPROVING FORCING JUST
NORTH OF THIS FRONT AS MID LVLS COOL. OVER SE CO MUCH THE SAME
CONDITIONS ARE ANTICIPATED LATE TUESDAY ALONG WITH THE ADDITION OF
A MOIST SE FLOW BEGINNING TO DEVELOP LATE THE DAY. GIVEN THIS WILL
CONTINUE TO FAVOR LATE DAY STORMS IN THE S/SE BUT PCPN IN THE SW
MAY LINGER INTO THE OVERNIGHT HOURS SINCE ANY ORGANIZED CONVECTION
THAT MAY DEVELOP SHOULD MOVE SSE ALONG THE THTE RIDGE AXIS/7H
BAROCLINIC ZONE. THE NEW 12Z NAM AND GFS HOWEVER KEEPS THIS THTE
AXIS FURTHER WEST AND SOUTH COMPARED TO PREVIOUS RUNS WHICH MAY
LIMIT HOW NORTHEAST THESE STORMS WILL BE IN SW KS WEDNESDAY NIGHT.
GIVEN THIS TREND FROM BOTH THE MODELS HAVE BEGUN TO SHIFT THE
BETTER OPPORTUNITY FOR PCPN A LITTLE FURTHER S/SW.

THURSDAY SHOULD BE MORE SEASONAL BASE ON 85H TEMPS AS A SFC HIGH
BEGINS TO BUILD INTO THE CNTL PLAINS AND A E/SE FLOW IN THE LOWER
LVLS CONTINUE THROUGH MUCH OF THE DAY.

DAYS 3-7...

THE MODELS REMAIN IN GOOD AGREEMENT DURING THE 3-7 DAY PERIOD AND
THEN BEGIN TO SHOW MORE SIGNIFICANT DIFFERENCES THEREAFTER. SMALL
POPS REMAIN IN THE GRIDS THU NIGHT INTO EARLY FRI AS THE OLD
FRONTAL BOUNDARY LIFTS NORTHWARD AS A WARM FRONT. THE BALANCE OF
FRI LOOKS WARM AND WINDY AS A NEW TROF DIGS INTO THE SW CONUS, A
RIDGE PUMPS UP OVER THE PLAINS, AND THE ASSOCIATED RESURGENT LEE
TROF CRANKS UP THE SW FLOW ACROSS THE PLAINS AGAIN. THE WRN TROF
THEN KICKS OUT INTO THE NRN PLAINS ON SAT WHICH PUSHES A FRONT
SOUTH THROUGH THE PLAINS. SAT WILL BE QUITE HOT AGAIN OVER SW KS
WITH HIGHS NEARING 100 OVER MUCH OF THE AREA. WILL INCREASE POPS
FROM THE NORTH LATE SAT INTO SAT NIGHT AS THE FRONT DROPS INTO WRN
KS AND HEIGHTS FALL.

HEIGHTS REMAIN LOW SUN AND GIVEN OUR PROXIMITY TO THE SFC BOUNDARY
WILL KEEP AT LEAST SLGT CHC POPS IN THROUGH MUCH OF SUN. THE UPPER
RIDGE THEN BEGINS TO PUMP UP AGAIN OVER THE PLAINS EARLY NEXT WEEK.
DESPITE HIGH HEIGHTS AND WARM AIR ALOFT, THE AMPLITUDE AND
ORIENTATION IS SUCH THAT COOL AIR COULD REMAIN IN PLACE AT THE SFC
OVER THE NORTHERN HALF OF THE PLAINS. UPSLOPE FLOW WILL ALSO SERVE
TO KEEP THINGS ON THE COOL SIDE AND THE MODEL SFC TEMPS ON BOTH THE
GFS/EC ARE INDICATIVE OF HIGHS ONLY IN THE 80S OVER SW KS. THE
PREVIOUS SHIFT PROBABLY HAD THE RIGHT IDEA THUS HAVE LOWERED HIGHS
BACK TO AROUND CLIMO FOR MON-WED. ALSO KEPT SOME SLIGHT CHC POPS IN
GIVEN UPSLOPE AND THE RESIDUAL BOUNDARY, BUT HEIGHTS ARE HIGH ENOUGH
THAT ANYTHING MORE WOULD LIKELY BE OVERKILL. -WRIGHT

&&

.AVIATION...

THUNDERSTORMS ARE ALREADY FORMING OVER THE HIGHER TERRAIN OF CO/NM
(AND EVEN AN ISOLD CELL OVER FAR WEST KS) WHICH WILL CONTINUE TO
GROW AND SPREAD INTO WRN KS THIS EVENING. HAVE INCLUDED VCTS AT ALL
TERMINALS BUT KGCK/KHYS ARE MOST LIKELY TO BE AFFECTED BY STORMS
THIS EVENING AND WILL UPDATE TAFS ACCORDINGLY AS STORM
TRACKS/COVERAGE BECOME MORE EVIDENT. OUTSIDE OF ANY STORMS, VFR
EXPECTED. STRONG SSW WINDS WILL CONTINUE AT ALL TERMINALS THIS
EVENING. A COLD FRONT WILL MOVE DOWN FROM THE NORTH LATE TONIGHT
WHICH MAY PRODUCE A FEW THUNDERSTORMS (PRIMARILY KDDC/KHYS) AND WILL
SHIFT WINDS TO THE NORTH AROUND 23/10-15Z. -WRIGHT
